I've spent entirely too much thought on the optimal contact sharing device.Business cards suck. I have stacks of them, I never remember why or how I got them, I have to transfer them into my contact list by hand and never get around to it. I'm sure others feel the same. NFC cards are better but the providers are all vultures who want to lock you into a subscription, put their branding on your stuff, or both. Plus if you give someone a card, they think they should keep it. That's no good! Them keeping your card is afailure state, you want it in their address book. Shrinking it down makes it cheaper and means there's no space for any branding.The tag and the QR code both simply open a URL. Tiny URL, tiny QR code. Dub makes 14-character URLs, which can be clicked up to 1000 times a month on the fre plan. I'm hosting it on github pages, which I already have and is also free.The site has four things: my bio, a button to download my VCard, a mailto link that launches their email client, and an SMS fallback. From the email, they can attach their vcard, fill in their own contact information, or send it as-is and get the name, email address, plus whatever might be in the email signature. An SMS is a bit shakier but has much the same idea.This interaction should take twenty seconds max, cost me nothing beyond the tags (which are super cheap) and the data only gets stored in my email, where I want it. A privacy win and I'm not relying on third parties I can't easily replace.
